Description
Technical field
This utility model is related to spectrometric instrument technical field, more particularly to a kind of diffuse-reflectance integrating sphere detection means.
Background technology
Integrating sphere is the hollow spheres that an inwall scribbles diffusive white reflective material, also known as luminosity ball, logical ball of light etc..Ball wall
On open one or several fenestras, as light well and place light receiving element receiver hole.The inwall of integrating sphere should be good
Sphere, usually requires that it should be not more than the 0.2% of internal diameter relative to the deviation of ideal spherical face.It is coated with ball inwall preferably unrestrained anti-
Material, that is, diffuse-reflectance coefficient are penetrated close to 1 material.Conventional material is magnesium oxide or barium sulfate, and it and colloid are glued
After mixture mix homogeneously, it is sprayed on inwall.Spectral reflectance of the magnesium oxide coating in limit of visible spectrum all 99% with
On, so, the light into integrating sphere forms the uniformity through inside coating multiple reflections on inwall.To obtain higher survey
Amount accuracy, the perforate ratio of integrating sphere should be as little as possible.Diffuse-reflectance is the main metering system of near infrared spectrum, and integrating sphere is tool
There is the hollow ball of highly reflective inner surface, can be with the solid sample to being in ball or be placed on outside ball simultaneously at certain window
Reflected light carry out high efficiency reception, its receive uniformity be that effect is reasonable in diffuse-reflectance adnexa.Diffuse-reflectance integrating sphere is surveyed
Amount system is particularly accuracy, sensitivity, the high precision of the testing result to heterogeneity test sample, while can guarantee that this kind of
The Model transfer effect of sample is good.
At present the shortcoming of integrating sphere detection means is the detection poor-performing to heterogeneity test sample, affects performance
Principal element has：The structure of integrating sphere, shadow mask, diameter, material, outgoing optical port diameter and detector etc..
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of diffuse-reflectance integrating sphere detection dress
Put, reduce measurement error.
This utility model for achieving the above object, is employed the following technical solutions：
A kind of diffuse-reflectance integrating sphere detection means, it is characterised in that：Including shell, integrating sphere, detector and specimen cup,
The integrating sphere is arranged on the enclosure, and the incidence window of integrating sphere is corresponding with the incidence window on the shell, product
Exit window on bulb separation is corresponding with the exit window on the shell；The detector is arranged on the side of the shell simultaneously
It is connected with the integrating sphere, the specimen cup is arranged in exit window on the housing, in the exit window of the integrating sphere
Baffle plate is provided between mouth and the detector.
Preferably, the exit window on the shell is provided with turntable, and the specimen cup is arranged on the turntable.
Preferably, the detector is deep into the inside of the shell.
The beneficial effects of the utility model are:Relative to prior art, the integrating sphere detector interface in the design can be with
Diffuse-reflectance fibre-optical probe is connect, so as to realize the detection to solid sample.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is the structural representation of shell in this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " horizontal ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " is based on accompanying drawing institute
The orientation for showing or position relationship, are for only for ease of description this utility model and simplify description, rather than indicate or imply indication
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
New restriction.
Reference picture 1- Fig. 3, a kind of diffuse-reflectance integrating sphere detection means, including shell 1, integrating sphere 2, detector 3 and sample
Product cup 4, the integrating sphere is arranged on the enclosure, the phase of incidence window 6 on the incidence window 5 of integrating sphere and the shell
Correspondence, the exit window 7 on integrating sphere is corresponding with the exit window 8 on the shell；The detector is arranged on described outer
The side of shell is simultaneously connected with the integrating sphere, and the specimen cup is arranged in exit window on the housing, in the integration
Baffle plate 9 is provided between the exit window of ball and the detector.Exit window on the shell is provided with turntable 10, described
Specimen cup is arranged on the turntable, the scope that wherein annulus 12 can be covered for a certain moment near infrared light, through rotation
The turning effort of platform, the scope that near infrared light can be covered is an annulus.The detector is deep into the inside of the shell.
Make detector recessed under certain condition so that incident illumination cannot be introduced into receptor, the effect shielded is replaced to a certain extent, from
And reduce error.The design use between sample and detector plus a baffle plate method reducing error.Due to
Necessarily with loss when integrating sphere internal light is propagated, from inverse square law, integrating sphere is bigger, the light in exit window
Illumination will be less.But integrating sphere is bigger, can effectively reduce other objects in screen and ball makes the shadow of integration ball denection ideal conditionss
Ring, improve the uniformity of illuminance at integrating sphere exit window, so as to improve measuring accuracy.
The design is suitable to the diffuse-reflectance integrating sphere in food, medicine quick detection application and its detecting system, is related to integration
The size of ball, inside opening, impact of the coating parameter to measuring, the best fit between research integration spherical structure and sample granularity
Relation, and the adnexa such as detector, specimen cup, the turntable for being related to match with integrating sphere.
Sample is placed at specimen cup, and infrared light 11 is reached at sample, is then diffused in the integration of a diameter of 50.8mm
At ball inner chamber 2, carry out multiple reflections and mix, a part is reached on detector, detector is used for the NIR carrying sample message
Optical signal is changed into the signal of telecommunication, then is changed into digital form output by A/D.Detector near infrared spectrum can be divided into
Two kinds of single-point detector and array detector.Response speed, sensitivity, the range of linearity are three leading indicators of detector.For
Reduce the uneven error for causing to measure due to sample, this utility model diffuse-reflectance integrating sphere detection system devises one
Turntable, for uneven granular solids sample, by the scan mode using rotation, increases scan area, so as to receive
Collect substantial amounts of sample message, it is representative strong, efficiently avoid medicine, the spectral error that food samples inhomogeneities are brought.
Shell 1 is installed and be assemblied in this utility model diffuse-reflectance integrating sphere detection system, and its size is 66.2*66.2*64.5mm.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
